' GEARING.

iniaasci.

To all whom t may concern n Be it known that I, CARL W. SwANsoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have inventedl certain new and useful Improvements in Gearing, of which the following is a specification.,

My invention relates to improvements in washing machines and has for its salient object to improve the construction and arrangement of the operating and gearing parts of a washing machine whereby the clothes-containing receptacle shall be 'oscillated by means of a novel arrangement of yielding power-transmission parts and whereby shifting of the power from oscillation of the receptacle to rotation of the i wringer in either direction may` be effected easily and with certainty.

Another object of my invention is to provide a machine which shall have the above mentioned and other advantages and which.

shall at the same time be of simple, cheap, and durable construction throughout.

Other objects of my invention will become readily apparent from a consideration of the following description taken in conjunction Iwith the drawings, wherein; Figure 1 is an end elevation of a machine constructed in accordance with my invention; Fig. 2 is an elevation thereof from the opposite end; Fig. 3 is an enlarged vertical section on line 3-3 of Fig. 1 through the powersupplying clutch mechanism, with the latch device shown in receptacle-engaging position; Fig. 4 is an enlarged section on line 4-4 ofFig. 2; Fig. 5 isa section of the yielding pitman, shown generally in Fig. 2; Fig. 6 is a section on line 6 6 of Fig. 1; Figs. 7 and 8 are top views of the latch, shown respectively in position to permit oscillation of the receptacle and in receptacle-engaging position; Fig. 9 is an enlarged elevation of the wringer-reversing mechanism shown at the top of Fig. 1; and Fig. l0 is a detail .of the cam membenof the wringer-reversing mechanism. K In the drawings, 15 and 16 indicate front and back frame strips or legs of stiff metallic construction, said strips at their lower ends bent to form feet 17. At each end of the frame, the strips converge toward each Specification of Letters Patent.

other andare riveted together at their tops, as at 18, so forming an end frame structure of lambdoidal shape. The strips are connected near the bottom thereof by longitudinal and transverse braces 19-19 and 20-2() .forming a horizontal generally-rectangular,

erablyY run diagonal braces or struts 21 from a point 22 on the rear strip 16, across the frame ends, each extending just above the braces 19 and 20. rllhe apices of the end frame structures are connected longitudinally by a wringer frame to be described.

T he clothes containing Vreceptacle 24, is constructed of sheet metal, and is suitably formed to perform its functions asa result of oscillation imparted thereto. At each end I secure to the receptacle a plate, each of'which provides a trunnion upon which the receptacle may be oscillated in the frame, and which may further provide the connections for the oscillating means and for they latch to be described. Specifically 26-26 indicate circular plates riveted to opposite ends of the receptacle and provided each with a trunnion 27 which rests jon an appropriate block 28 secured on the front leg 15 of the proximate end frame.

I prefer that the power. to oscillate the receptacle shall be applied thereto ata point remote from the aXis of oscillation, in order that the strains of carrying heavy loads of clothing and-water will not be imposed in too localized a fashion upon the sheet metal ends immediately adjacent'to the trunnioncarrying plate 26 and I further prefer that such power shall be applied to the recep-v,

tacle from an oscillating member having connection with the receptacle only through a spring which is laterally resilient l:in either direction. In the specic structure shown the trunnion plate 26 has an integral eX- tension arm 30y suitably riveted to the end wall of the receptacle and extending to a Patented ct. 12, 1915. V

' base-frame. For additional strength I prefvso v considerable distance from the center of oscillation, said arm at its extremity having an inturned ear 31 perforated for attachment of the power devices. Upon the trunnion 27 is loosely mounted a rocking lever 82, preferably having its power receiving arm 33 of yoke shape as shown in Fig. 4 for adequate bearing at two points upon the pitman be made longitudinally'yielding for.

trunnion 27, said lever having an extended power-applying arm 34 running forward in parallelism with the arm 30, said arm preferably terminating at a considerable distance from the ear 31. Between the extremities of the two arms 31 and 34 Ilprovide a spring connection preferably'in the form vof strong, laterally resilient coil spring 35 relatively stiff but capable of being bent transversely to curve its axis in either direction, said spring being secured to the end heads 36, which are respectively secured in the ears 31 of the receptacle arm 30, and to a pin 37 carried by the vibrating arm 33.A rIhis form of connection .permitsof spring? resisted lost motion between the receptacle 'and the vibrating lever, so that it is impossible to throw sudden strains and jars upon the receptacle -from violent'movements of the vibrating arm and conversely momentum acquired by the receptacle cannot lreact suddenlyo the vibrating arm.

The oscillating lever 32 is preferably operated from a drive shaft in the base of the frame through the intermediary of a crank and pitman, and it is my preference that the extension and compression.. In the drawings 38 indicates the power shaft mounted suitable bearings in the base frame end member 20, and carrying at its appropriate end a crank arm 39, connected by the pitman .40 to an appropriate arm 33 of lever 32..

The pitman 40 preferably consists of a Sleeve member 41 and a stem member 42 telescoping therein, said, stem `member sliding two springs 45 which extend toward abut against the bearing 43.

through a bearing abutment 43 fixed within the tubular sleeve member 41 and said stemv carrying above and below said abutment 43 heads to receive the opposite ends of and with the construction shown the pitman may be extended or compressed somewhat so that '1t acts as a shock absorber between the crank arm v39 and the rocking lever 32.v

Of course the receptacle, when lil-led with clothes and water, attains considerable mo# kvInentum that, tends to prevent reversal of Vthe direction of movement, and so further to ease the action of the de vice in order that some resistance may be interposed to the base plate 51, suspended centrally 'of the Manifestly member 56, splined upon the power shaft; f

and the opposite clutch member 57 of said gear-hub coperatingwith the clutch surface 58 of a clutch member 59 which is slidable and rotatable upon the sleeve 54, and has at its opposite end teeth 60 constantly engaged with teeth 61 on the hub of a sprocket wheel 62 loosely mounted upon sleeve 54, and adapte-d for operating the clothes wringer to be described.

The shipper arms 63 and 64 for the two clutch members 56 and 59, are secured in common upon a shipper bar 65, slidably mounted in suitable bearings in the frame members 2O and connected at its outer ends as` at 66 with a shipper lever 67 which is pivoted as at 68 at its lower end in a frame lug and extends up beside the `machine to convenient operating position. Manifestly b v throwing the handle of the'shipper lever 67 inward to its fullest extent the clutch 56.

is disengaged from the gear wheel 53 and the clutch 59 is engaged with said gear wheel 53, so that the driving mechanism for the clothes receptacle is not operated, but the driving gear 62 for the wringer is connected to the gear wheel 53 through said clutch 59.

"hen said shipper lever is moved to thev of the appropriate end frame, and in association therewith I- provide a latching device effectively 'cooperating' with both the oscillating body and the shipper lever so that when the body is locked the(shipper lever is also locked against movement to position to start the oscillating operation of the receptacle, thus insuring that the latch must be opened before/the operation of thereceptacle maybe started. Thus upon the bracket 70 I provide a bearing structure 71 in which is mounted a rotatable latch member 72 having its axis of rotation arranged at an oblique angle to the end of the receptacle 24. On the inner end ofthe latch member 72 is a small crank arm 73 with a latch nose 74 projecting to its eXtremity so that when the latch member is rotated to one positionv of movement of the shipper lever by the.

lockingv or unlocking movements respectively of the latch. The position of the pro-v jections 77 and 78 is such that they do not interfere with the movement of the shipper lever to its innermost (wringer-actuating) or central (neutral) position, but will positively prevent the movement of the shipper lever to its outer (receptacle-operating) position except when the latch isrotated to the position. shown in Fig. 8, when its nose 74: is completely out of the `path of the receptacle reinforcing arm 7,6. In this way positive provision is made for preventing the clutch being thrown to connect the power shaft to the motor while the latch is in locking position. The latch is so arranged in relation to its recessed arm that when the two parts are engaged the receptacle is held in upright position.

Upon the top board 79 of the machine, joining the apices of the end frames I mount a. clothes wringer 80 of usual con- Struction having one of its roller shafts 80 extend through a bearing block 81 carried by said board. On said shaft 80 I mount two opposed beveled gears 81 and 83 rotatable on the shaft, and between said gears I provide an idler pinion 84 mounted on the block 82 to communicate motion from one gear to the other. To the gear 82 I connect a sprocket 85, receiving power through chain 86 from sprocket 62. Each of the opposed gears 82 and 83 has its hub shaped to constitute a clutch member and between said4 opposing hub clutch I provide a central longitudinally shiftable clutch member 87 splined to the shaft 80. A central groove 88 of said shiftable clutch member is engagedV by a spiral blade 89 of an operating lever 90, pivoted in arms of the bearing member 82. For latching the clutch shifting blade 89 in any of its three positions I mounta round ended latch pin 98 in the recess 94 of the hub of the lever 90 and arrange-a spring 95 to press said latch pin outward so that it may engage any one of al series of holes 96 made in the side wall of its bearing frame. -y
